About Adam Callaghan
Callaghan IT Services Ltd was set up in 2013 as the company through which Adam Callaghan delivers independent consultancy work. It is a one-person UK practice. Engagements tend to be long-running and broaden as they develop, taking in additional projects and wider programme activity.
Adam has worked in IT since 1997. The first decade was spent in-house, designing, building, and running infrastructure across SQL Server farms, Active Directory, Exchange, Citrix, VMware, and the network and storage estates that supported them. The next seven years were spent as Infrastructure and Projects Manager at Jelf Group, integrating over fifteen business acquisitions into a corporate network of 35 sites and 1,100 users.
Since 2013, Adam has worked through Callaghan IT Services on a contracting basis, mostly on long-running engagements with UK Shared Business Services and the Ministry of Defence, alongside shorter engagements with Pro Global Insurance Solutions and the Arts and Humanities Research Council.
Throughout, Adam's work has combined solution architecture, delivery leadership where a programme needs it, and hands-on engineering.
Staying on through delivery
Many architects move on once a design is signed off, leaving the build, supplier coordination, migration weekends and handover to whoever is closest. Adam stays until the solution is running, the operations team has its runbooks, and the business is using it. That is why the work covers project management, training material and hands-on engineering as well as design.
On the network simplification programme, Adam took over project management when the original PM left early, worked the firewall migration weekends, and deployed and cabled network devices alongside the supplier's team. On the contact centre migration, that meant running project management for most of the programme while no PM was in post, alongside the security review, the SSO and provisioning dependencies, and the network design for real-time voice. On the change governance transformation, it meant building the front-door portal in Jira Product Discovery directly, then writing the training material that took users from submission through to delivery.
